Please i need help ASAP

Answer:

There is nothing wrong with the answer obtained

Step-by-step explanation:

Given the equation :

Y = mx + b

-2 = 3(4) + b

-2 = 12 + b

-14 = b

The correct calculation :

Y = mx + b

-2 = 3(4) + b

-2 = 12 + b

Subtract 12 from both sides

-2 - 12 = 12 + b - 12

-14 = b

Based on the details of the question given, the intercept, b is - 14 ;

Hence, there is nothing wrong with the answer

Coefficient of 14x is 14

Coefficientis the number in front of the letter. For example, coeffient of 2b is 2. When there is no number in front of the letter the coefficient is 1.

Answer: 64.8 mph

Step-by-step explanation:

Given

Arriving time is 6 hours

return time is 4 hours

The average speed of returning 81 mph

Distance traveled while returning

[tex]\Rightarrow d=81\times 4=324\ miles[/tex]

the average speed of the entire trip is

[tex]\Rightarrow v_{avg}=\dfrac{2\times 324}{6+4}=\dfrac{648}{10}=64.8\ mph[/tex]

The complete question is:

Erin loves to play sports! She has earned 3 tennis trophies, 4 basketball trophies, 7 soccer trophies, and 1 volleyball trophy.

What is the ratio of Erin's tennis trophies to soccer trophies?

This is simply the quotient between the number of tennis trophies and the number of soccer trophies.

She has 3 tennis trophies and 7 soccer trophies, then the ratio is:

The method of completing the squares method will be used for the next step. The next step would be ( x+ (b/2a)  )^2 = -c/a + b^2/(4a^2)

Suppose that two terms are 'a' and 'b'.

Then, their sum's square is expanded as:

[tex](a+b)^2 = a^2 + 2ab + b^2[/tex]

For this case, we're given the quadratic equation with its 4 steps of solution as:

[tex]ax^2 + bx + c = 0\\\\\dfrac{ax^2}{a} + \dfrac{bx}{a} + \dfrac{c}{a} = 0\\\\x^2 + \dfrac{bx}{a} + \dfrac{c}{a} = 0\\\\x^2 + \dfrac{bx}{a} = -\dfrac{c}{a}\\\\x^2 + \dfrac{bx}{a} + \dfrac{b^2}{4a^2} = -\dfrac{c}{a} + \dfrac{b^2}{4a^2}[/tex]

We've to proceed to the next step.

In the left hand side, we can use the formula [tex](a+b)^2 = a^2 + 2ab + b^2[/tex], where [tex]\rm a \: is \: x^2, and \: b \: is \: \dfrac{b}{2a}[/tex]

Thus, we have:

[tex]x^2 + \dfrac{bx}{a} + \dfrac{b^2}{4a^2} = x^2 + 2 \times x \times \dfrac{b}{2a} + \left(\dfrac{b}{2a} \right)^2 = \left( x + \dfrac{b}{2a} \right)^2[/tex]

We expressed the left sided expression in this form so that the variable 'x' (which is assuminly the only variable in the equation, whose value is to be known) gets packed into single container and not spread throughout with different powers.

Now, we can use square root and then subtraction and division of some terms which will make 'x' stay on one side of the equation, and rest of the constants on other side, as the value of 'x' for which the considered equation [tex]ax^2 + bx + c = 0[/tex] is correct.

The next step of the solution, therefore, is:

[tex]\left( x + \dfrac{b}{2a} \right)^2 = \dfrac{-c}{a} + \dfrac{b^2}{4a^2}[/tex]

Answer:

3 layers

Step-by-step explanation:

Given

[tex]L = 1cm[/tex] --- side length of the cube

Each layer = 2 * 2 cube

[tex]Volume = 24cm^3[/tex]

Required

Determine the number of layers

First, we calculate the volume of each layer:

The length of the layer is:

[tex]Length = 2 * L[/tex]

[tex]Length = 2 * 1cm[/tex]

[tex]Length = 2cm[/tex]

Next, we calculate the volume of each layer:

[tex]Volume = Length^3[/tex]

[tex]Volume = (2cm)^3[/tex]

[tex]Volume = 8cm^3[/tex]

The number of layer is calculated by dividing the volume of the tower by the volume of each layer

[tex]Layers = \frac{24cm^3}{8cm^3}[/tex]

[tex]Layers = 3[/tex]

Answer:

175 miles

Step-by-step explanation:

Average of 25 miles per gallon of fuel

Miles : gallons = 25 : 1

Predict how many miles they will be able to get from 7 gallons of fuel by using equivalent rates

Let x = number miles

Miles : gallons = x : 7

To find x

25 : 1 = x : 7

25/1 = x/7

Cross product

25*7 = 1*x

175 = x

x = 175 miles

Number miles = 175

Answer:

x = 3 and y = 8

Step-by-step explanation:

The Opposite sides of a parallelogram are equal and parallel. It means,

[tex]\dfrac{y}{2}=4\\\\y=8[/tex]

Also,

5x - 6 = 3x

Taking like terms together,

5x -3x = 6

2x = 6

x = 3

So, the values of x and y are 3 and 8 respectively.
